This informational message indicates that a JANUS rule has been applied to the indicated port and that the rule has pre-empted num previous rules applied to the port. An old rule would be pre-empted if parameters specified in the new rule would prevent the old rule from ever being examined. In the case of JANUS WEB rules, the parameters include the URL.

'Subcmd' indicates the JANUS rule command issued: WEB, CLSOCK, or SRVSOCK. 'Rule_type' indicates the type of rule being established, for example, ALLOW or ON. 
The JANUS rules are always evaluated in most recently issued order. 
Due to this, a JANUS WEB command where a wildcard URL contains the old URL as a subset will generally cause the old rule to be pre-empted. For example, the command "JANUS WEB WEBPORT TYPE * TEXT/PLAIN" would pre-empt the command "JANUS WEB WEBPORT TYPE *.HTML TEXT/HTML" because the URL's that match "*.HTML" are a subset of the URL's that match "*".
